This is the Trog / Sif Muna Rivals overflow vault. I think that Dowan and Duvessa fit this theme, since Dowan is a magician and Duvessa berserks if he dies. Their XP are 46 and 103 respectively. If they've already been placed, then an orc wizard and orc warrior have 37 and 133 XP respectively. Things I need help on:

I understand that Dowan and Duvessa are considered a single unique. I don't know their in-game name.

I do expect that they are placed with a single glyph, and like a band the other one is put into an empty space nearby.

I don't know the depth at which they, or orc wizards and warriors, begin to appear.

The orcs will not appear as bands unless I specifically say so, correct?

In general, where can I find the depth and name information for monsters? The wiki and LearnDB seem to give plain English names and no depth information.
